hand, use a carrying case (either an Epson case or something similar, 
such as a well-padded notebook case). See page 15 for ordering 
information, and page 108 for transportation instructions.

Setting Up the Projector
This chapter gives you basic information on setting up the projector: 
where to position it and how to connect it to a video source (such as a 
VCR or DVD player) or to a notebook or desktop computer. 
Follow the instructions in this chapter on:
■Positioning the projector
■Connecting to video equipment
■Connecting to a computer
■Connecting an external monitor
■Playing sound through the projector 
						

							18Setting Up the Projector
Positioning the Projector
If you’re setting up the projector yourself and it isn’t already installed 
in the theater or conference room you’re using, you’ll probably want 
to place it on a table in front of the screen, as shown.  x art below
This lets you stand in the front of the room, face the audience, and 
remain close enough to the equipment to be able to control it. Try to 
leave as much space as possible between the projector and the screen to 
get a good-size image. 
Use the figure below to help you determine placement. Image size 
increases with distance, but can vary depending on how you position 
the zoom ring and whether you’ve adjusted the image with other 
settings.
Also keep these considerations in mind: 
■Place the projector on a sturdy, level surface.
■Make sure there is plenty of space for ventilation around and 
under the projector. Do not set the projector on top of loose 
papers that could block the vents under the projector. 
■Make sure the projector is within 10 feet of a grounded electrical 
outlet or extension cord. 
note
You can mount the projector 
on the ceiling, or place it 
behind a translucent screen 
for rear projection. See 
page 123 for details.

							Setting Up the Projector19
Ideally, you should place the projector directly in front of the center of 
the screen, facing it toward the screen squarely. The base of the lens 
should be at about the level of the bottom of the screen.  
If you place the projector below screen level, you’ll have to tilt it up by 
extending its feet. This causes the image to become “keystone” shaped, 
but you can correct the distortion by pressing the 
Sync buttons on the 
projector. See page 44 for detailed information about correcting the 
image shape.
For instructions on installing the projector in a permanent location, 
such as a theater or conference room, see page 123.
note
After positioning the 
projector, you may want to 
connect a Kensington 
MicroSaver
® anti-theft 
device to the lock port on the 
projector’s left side. You can 
purchase this from Epson; 
see “Optional Accessories” on 
page 15.ScreenProjector 
						

							20Setting Up the Projector
Connecting to Video Equipment 
You can connect up to four video sources to the projector at the same 
time. Before starting, look at your video equipment to determine its 
available video-output connections: 
■If your video player has a yellow RCA-style video output 
connector, see “Connecting a Composite Video Source” on 
page 21.
■If your video player has an S-Video connector, see “Connecting 
an S-Video Source” on page 22.
■If your video player has a component video port (three connectors 
labeled either Y/Cb/Cr or Y/Pb/Pr), see “Connecting a 
Component Video Source” on page 23.
■If your video player has an RGB video port (either a single 
connector for a VGA-style monitor cable, or three connectors 
labeled R/G/B), see “Connecting an RGB Video Source” on 
page 24.
After connecting the video cables, you may also want to connect an 
audio cable to play sound through the projector; see page 33.
